Question

How much time would it take for the sound of thunder to travel 1,500 meters if sound travels at a speed of 330m/ sec?

Answer 1

330m/sec

Set up an equation:
330m/sec = 1500m/x

Cross multiply:
330m * x = 1500m/sec

Divide both sides by 330 to solve for x
(330m * x)/330 = (1500m/sec)/330

Simplify:
x = 4.545

So it would take about 4.5 or 5 seconds for the sound of thunder to travel 1500 meters.

Answer 2

time = distance / speed
time = 1500/330
time = 4.55 seconds <== (thats rounded)
